Whitman and Baudelaire
Examines the relation between Whitman and Baudelaire and contends that there is very little doubt that Whitman knew something about Baudelaire from his reading of (George) Saintsbury, but that Baudelaire likely knew little of Whitman and that it is doubtful that Baudelaire would have cared for the man or his poetry

Edge Intersection Graphs of L-Shaped Paths in Grids
In this paper we continue the study of the edge intersection graphs of one
(or zero) bend paths on a rectangular grid. That is, the edge intersection
graphs where each vertex is represented by one of the following shapes:
,, , , and we consider zero bend
paths (i.e., | and ) to be degenerate s. These graphs, called
-EPG graphs, were first introduced by Golumbic et al (2009). We consider
the natural subclasses of -EPG formed by the subsets of the four single
bend shapes (i.e., {}, {,},
{,}, and {,,}) and we
denote the classes by [], [,],
[,], and [,,]
respectively. Note: all other subsets are isomorphic to these up to 90 degree
rotation. We show that testing for membership in each of these classes is
NP-complete and observe the expected strict inclusions and incomparability
(i.e., [] [,],
[,] [,,]
-EPG; also, [,] is incomparable with
[,]). Additionally, we give characterizations and
polytime recognition algorithms for special subclasses of Split
[].Comment: 14 pages, to appear in DAM special issue for LAGOS'1
Evaluating regional emission estimates using the TRACE-P observations
Measurements obtained during the NASA Transport and Chemical Evolution over the Pacific (TRACE-P) experiment are used in conjunction with regional modeling analysis to evaluate emission estimates for Asia. A comparison between the modeled values and the observations is one method to evaluate emissions. Based on such analysis it is concluded that the inventory performs well for the light alkanes, CO, ethyne, SO2, and NOₓ. Furthermore, based on model skill in predicting important photochemical species such as O₃, HCHO, OH, HO₂, and HNO₃, it is found that the emissions inventories are of sufficient quality to support preliminary studies of ozone production. These are important finding in light of the fact that emission estimates for many species (such as speciated NMHCs and BC) for this region have only recently been estimated and are highly uncertain. Using a classification of the measurements built upon trajectory analysis, we compare observed species distributions and ratios of species to those modeled and to ratios estimated from the emissions inventory. It is shown that this technique can reconstruct a spatial distribution of propane/benzene that looks remarkably similar to that calculated from the emissions inventory. A major discrepancy between modeled and observed behavior is found in the Yellow Sea, where modeled values are systematically underpredicted. The integrated analysis suggests that this may be related to an underestimation of emissions from the domestic sector. The emission is further tested by comparing observed and measured species ratios in identified megacity plumes. Many of the model derived ratios (e.g., BC/CO, SOₓ/C₂H₂) fall within ∼25% of those observed and all fall outside of a factor of 2.5.
